'MULTITLE=TWA'Y FIXTURE CONNEGTJSNG PLURALIT'Y QFiPIYZF Application filed. July 18, @924- Serial :No. 726,890.

To aZZ whom it may cmwern;

Be it known that I, ALEXANDER BERN- HARD Dniienn, a German citizen, residing at Luhec-k Germany, have invented certain new and useful Improvements in; Multiple- Way Fixtures for Connecting a Plurality'of Pipes, of which the following is a specification.

The present invention relates to a multiple fixture for connecting a plurali y of pipes, as used particularly in breathing apparatus, and described in my prior -patent application Sen, No. 476238 filed June 9th 1921;. The multiple way fixtai-re disclosed by this prior application consists of two integ ral sections extending transversely to each other and provided with bores extending at approximately right angles to each other in different planes and eachconnected with one of saidpipes said gfi-xtnres further having a connectingohan-nel extending between said bores toic'onnect the same, and a valve in one oat the sections of the said fixture for controlling the communication behe novel --fea-tu re of the improved fixture forming the subject matter ot the present invention, consists in that ztrom the valve chamber act the section containing the, valve or control-ling the communication between the bores of this section and the main section, is branched ofi 'a third integral section the bore of whichis in oonnection with a. further pipe and controlled by a suitable;

preferably a self-closing stop valve. The

arrangement heing thus that the bore of the third section also after closing the controlling valve of the bore of the second or trans verse section remains always in o0inmunication with the 'bore of the main section, so that after opening the controlling valve of the third section communication is established between the bore of the main section andthe pipe connected :to the third section.

By means of the improved fixture it is therefore possible to tap or draw off any fluid from the main section to and through the third section, even if the second or transverse section has been shut off.

In the accompanying sheet of drawings is shown an example of the improved fixture constructed in accordance with and embodying the present invention. Fig. 1 is an elevation of the improved fixture in con.- nect'ion with the pipes of a self-contained breathing apparatus of which shown only as much as is necessary for the understand ing of the invention; Fig. 2 is a sectien on the line A-B of Fig, 1; and Fig. 3 is a section on the line CD of Fig. ,2. V J

Similar le'tters'of reference refer to 'like parts throughout the several views.

The fixture consisting of three integral sections, the main section a, the second :or transverse section 0 and the thir'dior auxilicary section In, is-fsitu-ated between the S1 91 valve '6 or the oxy en container 7 and the pressure reducing valve '4') off a se'l'gfecontai'neld breathing apparatus; In- Fig. 1 the controllin valve 9 the-seqondor transversesecftionc (see Fig; 2) is in the opened ;positio its operating lever It being capa' ble of bein ecured i this opened po ition against unintentional turning by fastening tween the bores of the sections a and 0 but off.

From the valve chamber '0 or the second section a the here of which is tranverse to the bore of the main section a, both bores extending t; about right angles to each other in different -plan'es and being in fc'oinniunica'ti'onhy a 1connectingbore"d, is

tranchedjofi a likewise integral third "secitjonk. The outlet end of the bore of this third or auxiliary section is held closed preferably by a self-closing valve consisting of aspring'a'ctu'ated bent lever p adapt fed to be opera-ted in well known manner by means' o f presebutton lofga's-tightly and 'rnovab'ly arranged the Trainingbf a win- "(low in the 'wall of 'a suitable cap m screwed upon the said section 70 and protectingthe valve mechanism 49 within the said cap m against influenc s from Witl'fdilt. From the cap at a r'ri'scharge "sodk'et branches on.

When the valve 6 of the oxygen container f and the valve 1; of the transverse section 0 are opened (Fig. 1), high pressure oxygen is passing through the main section a into the pressure reducing valve 6 from where low pressure oxygen for revivifying the breathing air is continuously passed through the pipe 1 into the air circuit-system of the breathing apparatus in a predetermined constant amount per unit of time. Besides t s sea hel Wil -91ml o y n P r aniliing requirements prevailing at the time. A

part of the oxygen flowing through the main section a, is passing'through the connecting bore d and the valve chamber also into the bores of the sections .0 and 7c and filling them up. As the section 0 is connected to a by-pass conduit 8 for the pressure" reducing valveb, said conduit .9

leading to the pipe 9 and being provided with a hand operated controlling valve for v example of the kind as fully disclosed in valve ;0 0.

' has become unavailable for supplying ad iditional high pressure oxygen, the transverse section cis closed by screwing home the controlling valve Q) (Fig. 2). In order I my prior patent application Ser. No. 476238, filed ,June 9th 1921, additional high pres sure oxygen may be periodically supplied.

through the pipe 9 into the air circuit systern of the breathing apparatus by opening the valve controlling the said by-pass conduit. Nb high pressure oxygen can discharge through the thirdsection 7: as long as its bore is keptclosed by the controlling If for any reason the bypass conduit 8 to supplyneverthelessadditional high pressure oxygen-into the air circuit system of the apparatus it, requires only a short opening of the controlling valve 7) by gently touching or pressing on the press-button 0 (Fig. 3). Oxygen is then passing at once through the bore of the section 7: into the interior of the cap m and from here through V the socket n,.the pipe I (Fig, l) and the by-pass conduit 8 into the pipe 9 and the air circuit systemof the apparatus respec tively. The additional supply of oxygen ceases, as soon as the press-button 0 is 'released and the valve 9 under the actionof the spring 72 automatically closes the bore of the section is.

I claim:

ing a plurality of pipes, consisting of three integral sections, the first and second of them extending transversely to each other and provided with bores extending at approximately right angles to each other in different planes and each adapted for connection with separate pipes, said fixture further having a connecting channel extending betweensaid bores to connect the same, a valve in said fixture for controlling the communication between said bores, the

third section extending from the second section at about right angles and provided with a bore emanating from the valve chamber of the second section, and a valve controlling the bore of the third section.

' 2. A multiple way fixture for connecting .a plurality of pipes, consisting of three inthird section extending from the second sec tion at about right angles and provided with a bore emanating from the valve cham- I ber'ot the second section, a cap extending over said third section, a self-closing valve mechanism mounted within said cap and controlling the bore of the third section, and a press-button for actuating said valve mechanism to open tlievalve.

3. A. multiple way fixture comprising a casing having first, second, and third bores in communication with each other, the exit end of the first .bore' being arranged to lead to one point and the second and third bores being arranged tolead to a common point different from the point to which the first bore leads, a first valve in said casing controlling the communication between said first and second bores and [a second valve controlling the communication between the third bore andthe point to which it leads, said second valve being operated, at will, to open said communication even I I v r when said first valve is closed.
